Side by side videos of (almost) one lap at Suzuka in GT5:Prologue and real life, driven by Schumacher. The Prologue car is the Ferrari F1 2007, while Schumacher is driving (presumably) the 2006 F248. Source videos from YT, original GT5 driver unknown. Schumacher is actually the faster driver so I had to speed up/slow down the GT5:P video in order for it to keep up with the real life video while making sure every part of the track is reached at the same time. The time modifications on the video are almost undetectable as they were never beyond +-10%.

UPDATE: Both videos linked above have been removed. The sound is from the real life footage.

AFTER EFFECTS HOWTO:1. Enable Time Remap function on footage you want to stretch2. Depending on time difference decide how often to set a keyframe, say every 10-20s.3. Set the keyframes on the Time Remap function at easily identifiable frames (kerbs hit, start lines, brake points, etc)4. Find the same spots in the unstretched footage and mark them5. Drag the time adjustment keyframes to match the markers set above, the software will do the rest
